MASTER auto-detection system at Kislovodsk detected a new transient source at the position (R.A., Dec) = 01h 53m 47.24s , +30d 38m 44s.0 (J2000) with a typical uncertainty of 0.2" at 2010-10-01 23:25:48 (UT).

The V magnitude is about 17.9 +-0.1 ( exposition 180s, m_lim = 19.0 ).

The OT is seen at next 7 images up 2010-10-12 in R and V. OT is blue: R-V=1.43 at 2010-10-01.9 .

There is no minor planet and any object brighter 21 mag in DSS at this place. We have a number images this field without OT. The last one was made at 2009-12-08 18:25:50 and have the limit V=19.4.

The nearest known galaxy is PGC1908869 (01h 53m 55.00s , +30d 33m 59.0s). The OT as the SN-candidate is relatively far and more brighter than possible host galaxy.

The spectral observations are needed.
